2-6. CONNECTING WIRES FOR INDOOR UNIT
You can connect indoor/outdoor lead wire without removing the front grille.
1) Open the front grille.
2) Remove panel.
3) Remove electrical cover.
4) Remove cord clamp.
5) Pass indoor/outdoor unit connecting wire (A) from the back of the indoor unit and
process the end of the wire.
6) Loosen terminal screw, and connect first the earth wire, then indoor/outdoor unit con-
necting wire (A) to the terminal block. Be careful not to make mis-wiring. Fix the wire
to the terminal block securely so that no part of its core is appeared, and no external
force is conveyed to the connecting section of the terminal block.
7) Firmly tighten the terminal screws to prevent them from loosening. After tightening,
pull the wires lightly to confirm that they do not move.
8) Secure indoor/outdoor unit connecting wire (A) and the earth wire with the cord
clamp. Never fail to hook the left claw of the cord clamp. Attach the cord clamp se-
curely.

• Make earth wire a little longer than others. (More than 55 mm)
• For future servicing, give extra length to the connecting wires.

2-7. PIPE FORMING AND INSTALLATION
Pipe Forming
• Route the drain hose diagonally below the connecting pipes.
• Make sure that the drain hose is not routed upward and that there are no waves in
the hose.
• Do not pull the hose when applying the tape.
• Route the piping so that it does not project past the rear of the indoor unit. (Refer to
the figure to the right.)
Connecting Pipe Installation
• Install the connecting pipes so that the piping can move slightly to the front, back,
left, and right.

• Be sure to insulate the connecting pipes and place them near the rear of the indoor
unit so that they do not contact the front panel.
• Be careful not to crush the connecting pipes when bending them.

FOR LEFT OR LEFT-REAR PIPING
Bundle the connecting pipes and drain hose together, and then wrap them in felt tape (11).
Cut and use the lower side panels on the left and right sides of the indoor unit as shown
below.
Smooth the cut edges of the side panels so that they will not damage the insulation coat-
ing.
• For left or right piping
• Installing flush against a wall with molding
Molding
Cut the lower side panels to match the
height of the molding.
Wrap the felt tape (11) tightly around the pipes and hose starting near where the
pipes and hose are routed from the indoor unit. (The overlap width of the felt tape (11)
should not be more than 1/2 of the tape width.)
Start wrapping the piping tape (G)
around the pipes and hose 10 mm
inside the indoor unit.
Fasten the end of the felt tape (11) with
a bandage stopper.
Make sure that the drain hose
is not routed upward.
